15m and 30 m
15m square is equal to 2,250,000 cm square. Note though, that 15m square is not the same as 15 square metres.
The GCF is 15m.
To evaluate 15m for m equals 7, you simply substitute 7 in place of m in the expression. So, 15m becomes 15 * 7. Multiplying 15 by 7 gives you the result of 105. Therefore, 15m, when m equals 7, is equal to 105.
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the rectangle has two sides of length 20m and two sides of length 15m. Therefore, the perimeter would be 2(20m) + 2(15m) = 40m + 30m = 70m.
